It is the first U.S. state to pass a measure of this kind. The ban starts immediately but must be renewed early next year. The measure expands on a current ban in Michigan, prohibiting sales to underage consumers. Under the ban, flavored e-cigarette products are not allowed to be sold in retail spots or online. State businesses have one month to follow the rule. Michigan Governor Gretchen Whitmer says the ban is meant to protect younger people. She has even declared a public health emergency in the state over rampant underage use. My number one priority is keeping our kids safe and protecting the health of the people of Michigan, Gretchen Whitmer, via 'The Washington Post'
